Specification of Letters Patent.

Patented Oct. 1%, 1917.

Application filed June 30, 1915. Serial No. 37,354.

To all whom it may concern.

Be it known that I, MYLns F. MORAN, a citizen of the United States, and resident of Lynn, county of Essex, State of Massachit setts, have invented an Improvement in Dies and Die-Stocks, of which the following description, in connection with the accompanying drawing is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in combined tools and particularly those of the type which are employed by plumber-sand other artificers in metal.

in performing repair work on plumbing and the like the workman is required either to carry a large number of tools such as dies, taps, wrenches, cutters, drills, etc, or else is likely to find it necessary to return to the shop for the proper tools for his work, for the reason that when he is sent out upon-a job he is unfamiliar with the type of plumbing which he is to repair, and since different buildings have plumbing materials of different kinds no one set of stock tools has been devised which are adapted to perform the work required upon the various types and sizes of fittings.

The principal object of the present invention is to provide a compound tool comprising a head and an actuator therefor which may be used in connection with various accessories easily contained in the usual plumbers kit which will enable the workman to readily repair almost any defect which he may find without the necessity of returning to the shop for the proper tools or taking the parts of the installation to the shop for threading, boring, cutting or other repair.

By the provision of such a compound tool it will be readily understood that much time otherwise lost will be saved and inconvenionce resultant upon the shutting off of water or gas fora relatively long period of time will be overcome.

Vfith these ends in view the present invention comprises a rotatable head which may, if desired be made in sections and which is adapted to be actuated either by a handle or handles connected directly thereto or by a pipe wrench of the usual character but preferably of the Parmelee type. This head is designed to provide a screw thread cutter or to be utilized as a support for a chuck,

boring tool, such as an auger or drill, or as a member of a jack or in various other relations within the usual requirements of the plumber or other workman in metal.

While it is impossible to disclose in this application all of the uses to which the compound tool forming the subject matter of this invention is adapted to be applied, or all of the various forms which the com pound tool may take I have illustrated here in a few of the preferred embodiments and uses of the invention. It will however be understood that the claims of this application are to be construed to cover other forms as well as various and sundry uses to which the same may be applied within the scope of their terms and that the object of this invention is broadly to provide a combined tool capable of various uses'and operable by suitable actuators of various types in cluding the chain or strap wrench, the Parmelee wrench and various other types of wrenches.

In the preferred embodiments of the invention however the cutter is provided with two handles preferably in axial alinement, one or both of which are detachably secured to an intermediate fiexible member whereby one of said handles may be easily removed in case of necessity but both may be generally used to provide for an accurate operation of the various tools which are operable through the head which forms the salient portion of said compound tool.

Fig. 11 is a view of the head shown in Fig. 5 with adjustable threading dies assembled in the actuator shown in Fig. 1,

Fig. 12 is a detail view of the head shown in Fig. 11 in open or extended position,

Fig. 13 is a vertical longitudinal section of said head embracing the shank of a chuck, the latter being shown in elevation,

The compound too-l illustrated herein coinprises a tool carryinghead and a handle member or actuator adapted detachably to engage the same comprising, preferably a pair of handle members connected by a series of intermediate links in such a manner that the handles will be in axial alinement as illustrated in Figs. 1 and l.

As illustrated in 1 of the drawing the actuator comprises a handle or stem 1 having preferably a slotted enlarged end 2 provided with a shouldered projection 3. the slots in said end portion being adapted to receive extensions alof a link 5 forming one of a series of gripping members. a sleeve 6 preferably having knurled portion 7 being screw threaded upon said stem 1 and adapted to actuate a slide 8 which serves in cotiper tion with the shoulder 3 to lock the gripping mem ers the same as in the Farmelee wrench.

The link 5 is hinged at its opposite end to a link 9' which in turn is hinged to a link 10, the free end of the link 10 being provided with a projection or shoulder 11 adapted to be engaged by the shoulder 3 upon the end of a handle member The link 9 preferably is provided with a boss 12 to which a handle 13 is connected by a screw threaded union. The handle 1 may be de tachably secured to the link 5 by a pin 14 which preferably is provided with a split ring 15 (see Fig. 7) seated partly in a groove in the pin and partly in a groove in the hinge extension of the link 5.

As illustrated in Figs. 1 and 11 the links 5, 9, and 10 are shown as embracing and operatively engaging a head which is provided with inwardly extending thread cut ting members engaging the end of a pipe P.

The head, which forms one of the principal features of this invention is shown in detail in different forms in Figs. 5, 12 and 13. As shown in Fig. 3 the head 16 consists of a hollow cylindrical member having inwardly projecting ribs 20 provided adjacent one end with screw cutting teeth 21, the remaining portion preferably being smoothly concaved and forming means ada ted to guide the bi )e P or rod to be screw threaded. The depression or interval 22 between the ribs 2O serves the double purpose of forming a clearance for he chips which are cut by the thread cut-ting members and also providing a seat for a chuck for holding other tools which will hereinafter be described.

The exterior of the head maybe of convenient form but preferably is cylindrical and is provided with screw threaded portions 23, 94, at its ends and an intermediate preferably smooth cylindrical portion 25 adapted to be gripped by the tlexible members of the actuator above described.

As illustrated in Figs. 5, 1:2 and 13 the head may be constructed of a series, prefei erably three, longitudinal sections 527. 28 the adjacent edges of the sections being provided with interlocking projections 29, 30, which may be secured together by pins 31, the free ends of the links 26 and 28 being secured in proper relation by a dowel pin carried by one of the members entering a slot 33 in the other member.

lower portion of the cylindrical member until the end thereof engages the innermost cutters of the dies 21, the pipe being clamped against rotative movement. The actuator, which preferably is of the form illustrated in Fig. 1 but which may be a pipe wrench of the usual character such as a Stillson wrench, or a chain wrench, is then caused to grasp the smooth cylindrical portion of the head and the head rotated relatively to the pipe, so that the cutting dies thereupon engage and screw thread the end of the pipe in the usual manner.

During the screw threading operation the curved surfaces of the ribs 20 loosely engage the exterior of the pipe and maintain the cutters in proper position relatively thereto.

It will be obvious that the same operation may be performed by the use of the head disclosed in Figs. 5 and 12 and that the latter has an additional inherent advantage in that when the thread has been out the actuator may be removed and the head then opened and removed from the pipe without the necessity of backing the same off as is the case when an integral cylindrical head such as that shown in Fig. 3 is used.

In order to insure the proper feeding of the cutter upon the pipe I may provide a threaded collar such as illustrated in Fig. 9 which is provided at one end with screw threads 36 adapted to engage the screw threads 2-1 upon the end of the head opposite to that which contains the screw thread ing dies 21. The collar 85 is preferably internally screw threaded at its opposite end and provided with a bushing 37 having an aperture 38 of the diameter of the pipe to be threaded.

Set screws 39 preferably three in number passing through the collar and bushing may serve to center and hold the sleeve rigid in respect to the pipe. When the sleeve has thus been aiiixed to the pipe the head 16 is placed over the end of the pipe until the screw threads 24- thereon engage the threads 36 of the sleeve. It is then screwed up by hand until the cutters 21 reach the end of the pipe, whereupon the actuator is clamped upon the central portion 25 of the head and the head rotated. This rotative action causes the thread cutters toengage and cut the threads upon the end of the pipe. In the meantime the engagement of the threads of the head and 36 of the sleeve act as a feeding means and since these threads are of the same pitch as the threads of the die members 21 the cutter will be fed accurately along the pipe as the screw threads are being cut, thus forming quite as accurate a thread upon the end of the pipe as if the same were cut in a regular screw threading machine.

The external screw threads 23 at the end of the head also provide means whereby the tool may be used to cut threadsupon the end of a pipe located in an otherwise inaccessible place, as for example, in a hole in the floor beneath the surface thereof or in a partition or wall in which case an internally threaded tube may be screwed upon the end of the head so that the head may be inserted in the aperture or hole to engage the end of the pipe to be threaded and the head rotated by a suitable actuator applied to the projecting tube.

Frequently in plumbing repair work it is found necessary to bore a hole in some portion of the iron work or in the Wood work which lies adjacent to the piping which is being repaired or installed, which requires the use of a boring tool. The necessity for such apertures is rather infrequent and the workman will be without a boring instrument. In order to provide for such exigencies T have provided the head 16 above described with attachments which enable it to be used both as a boring instrument for wood or iron.

It will be remembered that the ribs 20 project inwardly from the inner conca'ved surface of the head leaving recesses therebetween which in the use of the cutting die form clearance spaces for the die. These recesses may also be used to receive ribs 40 upon the body 41 of a chuck, the grooves L2 intermediate of said ribs embracing the ribs 20. The body portion ll of the chuck may be made to fit tightly the interior of the head or if desired may be made slightly tapered to insure a tight fit, suitable jaws being carried in the body of the chuck to engage the stem 13 of any usual tool, the jaws being clamped thereupon in the usual manner by a knurled collar M of the usual type. The opposite end of the head in such case desirably is covered by a cap 45 which is provided with internal threads to engage the threads 3 of the head. 16. The cap -it5 may present a smooth surface 45* if a wood boring tool to be used and may be provided with a central screw threaded aperture 16 adapted to receive a tail stock 47 ha ring a conical end 1 8 which may be caused to engage a member of a clamp or any other suitable abutment.

hen the tool is used for boring wood the proper tool is clamped in the head and forced against the wood by the pressure of the hand of the operator against the cape?) the actuator being applied to the cylindrical portion of the head and the latter rotated either by a complete rotary or by a reciproeating movement of the actuator. If the head is to be used with a metal boring tool the tail stock will be retracted until it engages an abutment or the arm of a suitable clamp and the tool rotated in the same manner. In such case the rotation of the head may serve in a measure to feed the tool forward but probably the end 48 ofthe tool will rotate freely upon the abutment with which it has a small bearing surface engagement. in such case the tail stock 47 may be rotated by thrusting a nail or an awl into apertures i9 in the angular head 50 of the tail stock; or the tail stock may be rotated by a usual small wrench in an obvious manner.

The head 16 may also be used in connection with the usual form of screw cutting die, such as illustrated in Fig. 10, for cutting threads upon pipes smaller than those which may be cut by the usual die.

an ordinary type of die for cutting 1. s illustrated which is in the form of a squase steel block 51 having four inwardly extending thread cutting members Assuming for example that this die is adapted to ut the threads upon a one-inch pipe and the workman finds it necessary to cut the thread upon three-quarter inch brass or copper pip he head 16 may be screwed into the die A and actuated by the usual die which embraces the square die cutter. In such case the resistance between the threads on ,ie head 16 and the thread cuttingdies will be much greater than the r sistance of t metal of the softer -21, of the head 16 pipe age the cutt so that the pipe may be screw threaded without iniury to the main die In some ir -ces it is desirable to have means for c ig a tapered thread upon the end of a pipe. 1 have therefore provided an adjustable form of thread cutter wnich may be utilized dies, particularly of the e illustrated in t and 5, in which the thread cutters are supported upon pivotally connected nembers. Such an ad justablc cutter is illustrated in Figs. 6 and 12 in which the thread cutters 21* are formed upon steel members 53 which are mounted upon pivots 5- within recesses 55 in the inner walls of the members 26, 2-7, 28. The ends of the walls are apertured to receive screws having beveled heads 57 wnich are partially seated in the walls of the members 26, 237, 28 and partially in a. suitable recess or grooved portion 58 of the thread cutting member 21*. lt will be obvious that as the screws 56 are forced inwardly the thread cutting members 21* will be moved about their pivots 54 in such a manner as to provide the necessary taper.

The thread cutter 21* may be held in its recess by a suitable resilient means such as spring 55 seated upon a shoulder in the lower end of the cutter andin a suitable socket in the wall 26.

This spring will serve to hold the thread cutter 21* in its normal posit-ion but will yield as the screw 56 is driven inward to force the cutter into position for taper thread cutting. By forming the recess 55 a little dee ser than is necessary to conform to standard depth of thread the thread cutters 21 may be permitted to expand sufiiciently to permit the cutting of threads above as well as below the usual standard cut.

ll liile the preferred form of the invention comprises an externally cylindricall head which may be operated by a. wrench having flexible gripping members adapted to clasp and rotate the head either by a continuously rotative or a reciprocating movement it will be understood that the head may be provided. with a suitable integral handle or preferably with means whereby it may be detachably secured to a handle or plurality of handles. As illustrated in '2 the head 16 may as provided with a lug 60 having projections 61 adapted to fit the slots in the end 2 of the handle 1, the head being secured to the handle by the pin It the lug 6O desirably being provided with a shouldered portion 62 adapted to be engaged by the shoulder 3 on the end of the handle.

Another very convenient embodiment of the invention is illustrated in. Fig. 4 in which the head is composed of a series of sections 96 27 28* similar to those. illustrated in Fig. 5, the end of the section 26* being provided with extensions 63 adapted to fit the slots in the end 2 of the handle 1, being secured therein by the pin ll. In this case the cutters 21 are carried by the respective members 26 27* and 28 as described in reference to Figs. 5 and 6.

Inasmuch as the tool thus constructed is adapted mainly for thread cutting it desirably is provided with two handles extending in axial alinement from the opposite members 26*, and 27*. This construction may be made by providing a lug 6i upon the member 27*, the lug being preferably provided with internal screw threads 65 adapted to engage corresponding screw threads upon a handle 66 which may be of piping of standard size and gage, for eX ample three quarter of an inch piping so that the workman need not carry an additional handle, however, if considerable work is to be done with the tool it is desirable that a regular handle be employed. l his handle may, if desired, be equipped with a cylindrical oil can 67 which may be telescopically fitted therein, as illustrated in dotted lines, having anozzle 68 extending through a suitable aperture in the member 69 and adapted to discharge oil upon the die. By such an arrangement the die may not only be kept well oiled but if desired may be flooded to remove the chips and thus facilitate the action of the cutters.

lhread cutters constructed like those il lustrated in Figs. and 6 are particularly advantageous since upon the completion of the thread the sleeve upon the handle 1 may be unscrewed, releasing the locking slide 8 and permitting sectional cutter to be removed from the work without the necessity of backing the same off. Furthermore the cutter when thus removed and opened as illustrated in Fig. 7 may be conveniently cleaned.

Many other operations may be performed by the mechanisms above described with or without the use of accessory tools. F or example the pin it may be partially with drawn from its socket and a. wire or rod placed between the pin and head may be bent into any convenient form. The tool is particularly useful in this manner in preparing hangers for pipes and the like since the rod maybe either bent around the pin to form an eye or bent aromid the head to form a loop or may be bent slightly or straightened by the leverage which may be obtained thereon between the pin and the head.

Furthermore suitable cutting devices may be attached to the end of the handle for the purpose of shearing small rods, wires, etc, or a pipe cutter of a usual type having suitable lugs to engage the slots in theend of the handle may be provided and used as an auxiliary tool. The tool may also be used as a jack for the purpose of el rating or spreading objects such for example as elevating a sink or for bending a pipe which is in the way of the workman. In such case the ends of the handles illustrated in Fig. 1 or at may be placed in such a manner as to abut against the object which it is desired to moveaud against another stationary object and a short pipe 'hrust into the head, serving as a handle may be used to rotate the compound tool about the axis of the handles. If in such case one of the handles is held from rotation by the operator the unscrewing of the handle from its socket will serve to move the object in the manner desired.

Likewise a piece of pipe having a notched end adapted-to engage the cross bars of a bath tub outlet plug seat may be substituted for one of the handle members and the tool rotated in the manner aforesaid to unscrew the plug seat. By this arrangement a powerful tool is provided by which the plug seat may be removed without danger of injuring the enameled tub, which frequently is seriously chipped when improper tools are used for the purpose of removing the plug seat.

The actuator, such as that illustrated in Fig. 1 may also be used conveniently as a vise to hold a pipe or other articles while they are being screw threaded or operated upon in other usual ways. This can be accomplished by unscrewing the handle 13 and screwing the boss 12 or extension of the part 9 upon the hose bib end of the faucet. The pipe to be held from rotation may then be placed within the jaws in the manner all of the operations necessary over above described and held clamped therein by pressure by the workman upon the handle 7 of the tool. The free end of the pipe may thereupon be threaded in the usual manner by the use of a thread cutter such.

workman may readily perform practieallv so that the chips, oil, etc, may fa l the sink or a paper or receptacle placed therein so that the same may be easily removed." 7

Various other uses may be made of this compound tool and the parts thereof as will be obvious to any workman skilled in the art of plumbing. It will therefore be an derstood that the mechanisms shown herein are illustrative of the invention merely and not restrictive and that the invention may be embodied in many other forms or adapted to many other uses within the meaning and scope of the following claims.
